If you have the webproxy feature on your Vyatta enabled, you might run  into the problem, that your Harmony Software doesn't work anymore.

You'll see a message "Unable to display Content" evenrytime you try to log into your account, no matter whether you use the Application itself or the Webinterface.

This is because Harmony can't properly deal with Proxies, that mean, ANY kind of proxies, so you might have this problem as well if your ISP is using some kind of transparent proxy. Although I can't help you with your ISP, there is a solution for the Vyatta Config making it work fine again.

The first thing you should to is to do a nslookup on "myremotesetup.com". For me this is on IP 74.201.85.121/32, it might be a different one for you, so check this out before.

Then do a 

set service webproxy proxy-bypass 74.201.85.121/32

That should be it, try again, it should work, at least it did for me.
